Full job description

At CGI, we deliver secure, innovative technology solutions that help our clients tackle complex challenges and achieve meaningful outcomes. As a Senior Python Developer, you’ll help build and support cloud-native applications that power critical services, working with modern technologies in a collaborative environment where your ideas, expertise, and contributions will make a real impact. You'll have the opportunity to influence engineering best practices, drive continuous improvement, and develop your career alongside experienced professionals.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named a UK ‘Best Employer’ by the Financial Times. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. This is a hybrid position.

Your future duties and responsibilities

As a Senior Python Developer, you’ll design, build, and support secure cloud-native applications within AWS environments. Working closely with product, platform, and engineering teams, you’ll help deliver scalable solutions while embedding security, automation, and operational excellence throughout the development lifecycle.

Develop secure Python applications and services
Build and enhance AWS cloud solutions
Create and maintain CI/CD pipelines using GitHub Actions and related tools
Develop Infrastructure as Code using Terraform
Implement secure development practices and automated security controls
Monitor, troubleshoot, and optimise application performance
Support incident investigation and service reliability
Collaborate with teams to improve engineering and platform practices
Participate in an on-call rota once established in the role

We're looking for someone with strong Python development experience and a passion for building secure, scalable cloud solutions.

Commercial experience developing applications with Python
Hands-on experience with AWS cloud services
Experience with Terraform or other Infrastructure as Code tools
CI/CD pipeline experience (GitHub Actions preferred)
Strong understanding of secure software development practices
Experience with observability, monitoring, or logging tools
Ability to investigate and resolve production issues

Together, as owners, let’s turn meaningful insights into action.

Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…

You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.

Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.

You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.

Come join our team—one of the largest IT and business consulting services firms in the world.
